Specification of Letters Patent.

Patented July at, 19115..

Application filed May 20, 1912. Serial No. 698,509.

To all whom it may concern Be it known that I, THOMAS P. ADAMS, acitizen of the United States, residing at Chicago, in the county of Cookand State .of Illinois, have invented certain new and usefulImprovements in VVater-Stills, of which the following is aspecification.

My invention relates to improvements in water stills, the presentembodiment of the invention being particularly designed and adapted fordomestic use.

The primary object of the invention is to provide a generally improvedwater still of this class of exceedingly simple, cheap, and efficientconstruction, the principal working parts being particularly designedand adapted for use in combination with ordinary household or kitchenutensils such as an ordinary tea kettle as a generating or vaporizingvessel and an ordinary pan for the reception of cold water for use as acondensing pan or vessel.

With the above mentioned and other ends in view, the invention consistsin the novel construction, arrangement, and combination of parts,hereinafter described, illustrated in one of its embodiments in theaccompanying drawings, and particularly pointed out in the appendedclaims.

Referring to the drawings forminga part of this specification, Figure 1,is a view partly in side elevation and partly in central verticalsection, of a water still constructed in accordance with this invention.Fig. 2, a top plan view of the vapor receiving pan detached. Fig. 3, asimilar view of the drip pan used in the vapor receiving pan below thecondensing pan or vessel.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

The improved water still comprises a still head 1, having an upwardlyextending vapor conduit pipe 2, the latter extending upwardly from thedome member 1 of the still head, said still head being adapted toreceive the vapor from the subjacent generating vessel 3, such as anordinary teakettle as shown in the drawings.

The lower end of the sti-llhead is preferably reduced or flared asshown, and is preferably provided with a supporting ring 4, resting uponthe generating vessel or kettle 8, for supporting the water still as aWhole, as well as adapting the lower end of the still head to kettles orgenerating vessels with varying sized lid openings.

The liquid receiving vessel 5, is preferably cylindrical or cup-shapedas shown, and is mounted above and secured to the still head 1, saidreceiving vessel being provided with a centrally located tubular member5, said tubularmember having its upper edges secured about the vaporconduit pipe and having its walls diverging or flaring downwardlyforming an annular insulating space 5*, about the walls of the vaporconduit pipe 2, as shown.

The vapor conduit pipe 2, is preferably provided with a. slidablymounted adjustable extension pipe 2, said extension con duit pipe 2being adapted to be adjusted so as to convey the vapor or steam more orless directly beneath the bottom of the condensing pan or vessel 6,which condensing pan 6, may comprise an ordinary kitchen pan adapted toreceive and contain the cold water or condensing medium.

The vapor receiving pan or vessel 7, is adapted to be removably mountedimmediately above the liquid receiving vessel 5, and is provided in itsbottom with a centrally located opening 7 to receive the extension pipeportion 2 of the vapor conduit pipe 2, and a plurality of liquid inletopenings 7 for the conveyance of the distillled water into the subjacentreceiving vesse 5. I

The vapor receiving pan or vessel 7, is provided with a funnel ordish-shaped drip pan 8, said drip pan being provided with a centralopening 8, to receive and contain the extension portion 2 of the vaporconduit pipe and a plurality of openings 8*, communicating with theinterior of the vapor receiving pan or vessel 7. The vapor receiving panor vessel 7 is also provided about its rim with a plurality of openings7, and the drip pan 8, is provided with a flattened rim portion 8,adapted to rest upon the beaded rim of the vapor receiving pan andextending over the same to support the superposed condensing pan 6, saidrim portion 8, when moistened by the vapor in the vapor receiving panforming a water sealed joint.

The liquid receiving vessel 5, is preferably provided about its uppermarginal edges with openings 5, which permit of an air circulationtherethrough and through the invention will'be readily understood.

ceiving vessel, and a centrally located upwardly converging tubularmember carried by said vessel and spaced from and surrounding said vaporconduit pipe forming an annular converging insulating space be-. tweenthe walls of said conduit pipe and said tubular member. I

2. In a water still, aliquid receiving vessel provided witha centrallylocated downwardly flaring tubular member,'a still head carried by saidvessel and provided with a dome shaped member below said tubular member,a vapor conduit pipe extending from said dome shaped member and spacedfrom and extending through said tubular member, and an extension pipeslidably and adjustably mounted in said vapor conduit pipe.

3. Ina water still, a liquid receivingvessel provided at its bottom witha still head, including a centrally located vapor conduit pipe extendingupwardly through said liquid receiving vessel,vsaid pipe being providedwith an adjustable extension pipe, a vapor receiving pan removablymounted above said liquid receiving vessel and provided with an openingtaking over said adjustable extension pipe, a perforated funnel shapeddrip pan removably mounted above and extending within said vaporreceiving pan and provided with an opening taking over said adjustableextension pipe, and a condensing pan removably mounted above said drippan and immediately above said adjustable extension pipe.

4. A water still, comprising a generating vessel, a still head having anupwardly extending vapor conduit pipe, a removable vapor receiving panhaving an opening surrounding said vapor conduit pipe, a condensing panremovably mounted above said vapor receiving pan and immediately abovesaid vapor conduit pipe, a perforated drip pan removably mounted in saidvapor receiving pan and supporting said condensing pan, and a liquidreceiving vessel below said vapor receiving pan and provided with anupwardly converging tubular member spaced from and surrounding saidconduit pipe.

5. A water still, comprising a generating vessel, a liquid receivingvessel provided with a subjacent still head having a vapor conduit pipeextending upwardly therethrough, a downwardly flaring centrally locatedtubular member within said liquid receiving vessel and surrounding andspaced from said apor conduit pipe, a vapor receiving pan removablymounted on said liquid receiving vessel and provided with an openingimmediately above said vapor conduit pipe, a drip pan removably mountedupon and depending within said v: por receiving vessel and provided witha centrally located opening, a condensing pan removably mounted abovesaid drip and vapor receiving pans, and an extension pipe adjustablymounted in said vapor conduit pipe and extending through the openings insaid vapor receiving and drip pans, said extension pipe being adjustabletoward and from said condensing pan to vary the condensing space belowthe latter.

In testimony whereof I have allixed my signature in presence of twowitnesses.
